ACHECKOR PUMZP VA LVE.

SPECIFICATION formingpart of Letters Patent No. 702,223, dated June 10,1902.

Application filed May 22, 1901.

To aZZ whom it may concern.-

Be it known that I, RICHARD KREHER,a subject of the Emperor of Germany,residing at Braidentown, in the county of Manatee and State of Florida,have invented certain new and useful Improvements in Check or PumpValves; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention relates to that class of valves which rest upon a flatseat and which are guided in theirmovement to properly reseat.

Figure 1 is a vertical sectionthrough a liftpump, showing my valveattached thereto. Fig. 2 is a top view of the guiding-disk. Fig. 3 is anenlarged sectional View through the valve, and Fig. 4is a bottom view ofthe sup-' porting-disk.

A is the barrel of the pump or may be the.

tion of a leather disk, with a supporting-disk end of a pipe, which isprovided with flange B for securing the seat to the same by theclamping-disk D and the bolts E. The seat 0 is formed by flanges on ashort pipe F, to which a service-pipe G is attached. The valve Hconsists of the leather or other pliable disk I), the supporting-disk a,the guidingdisk d, provided with perforations within the Thesupporting-diskis provided with the annular Serial No. 61,416. (Nomodel.)

rib f, which in cross-section is round on its outer face, which pressesupon the leather disk where it comes in contact with the seat, insuringa close fit of the valve, and thereby preventingleaking of the same. Theguidingdisk 01 is placed on the supporting-disk a, and the two are heldsecurely together and to the leather disk I) by the bolt e. The guidingdisk is of greater diameter than the supporting-disk and pump barrel orpipe, which is enlarged to receive the same and forms a stop g, againstwhich the guiding-disk strikes to limit the lift of valve. ,Theguiding-disk is provided with openings or perforations h where itprojects over the supporting-disk for the passage of fluid when thevalve is ofi the seat.

5 Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a check or pumping valve the combinaprovided with an annular rib aperforated guiding-disk and a bolt for clamping same together. p

In testimony whereof I affix my signature in presence of two witnesses.
